Description

Technical Field

[0001] The invention belongs to the technical field of daily necessities, and particularly relates to a method for preparing highly urine-absorbent and highly breathable pull-up pants for babies. Background Art

[0002] At present, due to their ease of use and reasonable price, most parents choose to use diapers for their babies instead of traditional diapers. Diapers are a general term for paper diapers, paper diapers and pull-up pants. Pull-up pants are like small underwear, which can be put on with a pull and taken off with a tear. They are very suitable for active babies who are beginning to roll over, crawl or walk.

[0003] In order to ensure the baby's comfort, pull-up pants need to be made of materials with strong moisture absorption ability and good breathability. However, the materials used in existing pull-up pants generally have a single structure. After absorbing urine, water molecules fill the gaps between the molecules in the water-absorbing layer, and the breathability decreases. After the urine reversely permeates into the inner base fabric layer, it is easy to cause discomfort to the baby.

[0004] In view of the shortcomings of existing technologies, improvements need to be made. Summary of the invention

[0005] In view of this, the object of the present invention is to provide a method for preparing highly urine-absorbent and highly breathable pull-up pants for babies to solve the above-mentioned problems.

[0007] Preferably, the body of the pull-up pants comprises, from the outside to the inside, a surface non-woven fabric layer, a breathable layer, a first liquid-repellent layer, a first moisture-conducting layer and an inner base fabric layer, the second moisture-conducting layer and the third moisture-conducting layer are alternately distributed on the upper side of the inner base fabric layer, the second liquid-repellent layer is arranged on the upper side of the second moisture-conducting layer, a water-absorbent layer is arranged on the upper side of the second liquid-repellent layer, the third liquid-repellent layer is arranged on the side of the water-absorbent layer, the upper side of the water-absorbent layer is bonded to the lower side of the first liquid-repellent layer, a hemp rope net is arranged on the upper side of the third moisture-conducting layer, a fourth moisture-conducting layer is arranged on the upper side of the hemp rope net, and the upper side of the fourth moisture-conducting layer is bonded to the lower layer of the first liquid-repellent layer.

[0008] Preferably, the breathable layer is a mesh structure woven from highly elastic fibers.

[0009] Preferably, the first liquid-repellent layer and the second liquid-repellent layer are liquid-repellent microporous membranes.

[0010] Preferably, glue guns are arranged side by side on the pull-up pants production machine, which are specially used for scraping glue on pull-up pants. The glue spraying width of the glue gun is 200 mm, the aperture of each nozzle of the glue gun is 25 mm, the distance between the glue spraying holes is 3 mm, and the glue gun adopts a solenoid valve to control the glue discharge;

[0011] The inner base fabric layer of the main body is used as the base layer, and the alternately distributed second moisture conductive layer and the third moisture conductive layer are pasted to the inner base fabric layer by using a pull-up pants glue gun, the second liquid repellent layer is pasted on the upper side of the second moisture conductive layer, and the hemp rope net is pasted on the upper side of the third moisture conductive layer, and the edges of the hemp rope net and the second liquid repellent layer are sprayed with glue to adhere the hemp rope net and the second liquid repellent layer to form the surface layer of the pull-up pants;

[0012] Using the surface layer of the main body as the base layer, glue gun is used to glue the breathable layer, the first liquid repellent layer and the first moisture conducting layer in sequence to form the inner layer of the pull-up pants;

[0013] The water-absorbing layer, the third liquid-repellent layer and the fourth moisture-conducting layer are alternately distributed, and glue is sprayed between the edges of the water-absorbing layer, the third liquid-repellent layer and the fourth moisture-conducting layer using a glue gun, so that the water-absorbing layer, the third liquid-repellent layer and the fourth moisture-conducting layer are adhered together to form the middle layer of the pull-up pants;

[0014] Align the water absorption layer with the second liquid repellent layer, align the hemp rope net with the fourth moisture conducting layer, adhere the lower side of the middle layer of the pull-up pants to the inner layer of the pull-up pants, and then adhere the surface layer of the pull-up pants to the upper side of the middle layer of the pull-up pants as a whole;

[0015] The eccentric wheel cuts the trousers into the shape of the trousers body, and transmits them to the guide wheel and folding plate through the negative pressure conveyor belt, and folds are pressed out on the edge of the body to form the waist edge.

[0016] The upper and lower edges of the main body obtained in the previous step are sprayed with glue to obtain end sealants, and then the glue is scraped between the two end sealants to obtain several groups of parallel glue strips; finally, the highly urine-absorbent and highly breathable baby pull-up pants can be obtained.

[0017] The beneficial effect of the present invention is that after the present invention is worn by infants and young children, urine passes through the first moisture conductive layer, the second moisture conductive layer, the fourth moisture conductive layer and the first moisture conductive layer in sequence and is then absorbed by the water absorption layer. At the same time, the gap in the middle of the rope body of the hemp rope net soaked with urine is filled with urine water molecules, the hemp rope net is stretched, and the first moisture conductive layer is tightened at one end close to the hemp rope net to prevent urine in the fourth moisture conductive layer from flowing back to the second moisture conductive layer and the third moisture conductive layer, and the second liquid-repellent layer is used to separate the water absorption layer from the inner base fabric layer to keep the inner base fabric layer dry and improve comfort.
